Hey, i am currently making some Websites for my Server using UmbAccess.

I am always getting this error when trying to send 8193 Characters (8192 are working)

Does someone know how to fix this?

I'd imagine the solution is to not send more than 8192 characters. It seems like a somewhat arbitrary cap to me (it's 2^13, so three bytes and a bit), but if that's all you're able to send then there's probably a reason for it.
